'TRUCK SIDE-FRAME.

- Application'filed llpril 30,1920. Serial No 377,826.

To all whom it mag "concern."

Be it known that I, DONALD S. BAR'noWs,

State of New York, have inventedcert'ain new} and useful Improvements-in "Truck Side Frames and I do hereby'declare the flspeeifi'cation; 4

following tobe a full, clear, andgexact descriptionof-the invention, su'chaswi'll enable othersskilled in theart a which it}.

appertains to make and use the same.-

'The invention relates to. trucksfor rail:-- way vehicles and more particularlyto new' and useful improvements in the construction of truck side frames.- I

The, principal object of my] invention, broadly stated, is toimprove the construe? tion of truckside frames of the arch; bar type. T0 this end the main features of the invention consist in arranging the compres sion and tension members so-that the points; of intersection thereof lie closely adjacent to the vertical planespassed through. the

truck axles. and in inter-posing betweenfthe said members a. new. and improved-form .of

. combined: strut, bolster guide and-spring plank support. Another feature of the invention resides in the form and arrangement of compressionand tension members of the side frame.

the brake hanger bracketyand Fig. 8 is a Still another feature of the invention confsists in interposing between each journal box and the adjacent ends of the compres -l'e sion and tension members a journalbox seat adapted to cooperate withthejsaid. members and to afford a strong and simple connect mg means betwe'en'the same and to provide a simple and efficient means for connecting the journal boxes to. the side frames.

"Still another feature of the inventioncon sists inproviding a tension member oomposed of a plurality offlflanged members, or

bars the opposite ends of which. are 'connected to the compression :member. adjacent the 7 ends thereof, the cross sectional 1 area of the end portions ofthe sa'id flanged members being at; least equal to the cross sectional area-thereof. at a point intermediate the said end portions. I

Still another feature of he invention consists in providing a strut member with removable wear plates and brake hanger brackets.

Another primary feature of the invention brake. hanger bracket;

"journalbox seats. I. '3 Figs. 11 and l2illustra'te a' slight modifi 'cation in the formand mann'er' of connecting resides in the construction of the journal" box tie members.

To-these and other ends the invention consists in certain improvements and c'ombinaf ,tlons of parts as will be heremafter'more Referring now, drawings wherein I have illustrated a single embodi h inventio p i g --F'gure 1 is'a'perspective vie wgshowingthe outer face o.f-}-acomplete .s'ideframe eons,

Fig, 12 a view in vertical section, showing the guide plate in 'positionl' I by like ref Throughout the specification and drawdesignates generally the a hollow "box. member having a top member 4, upright columns5, 5 and a bottommem her 6, all of which will hereinafter be more fully described. The lower arch or tension member preferably comprises a pair of flanged bars 8, 8. the said bars being adapted to extend under the strut member and to have their ends .connected to the tension member 2 adjacent the end portions 9 there-- of. The lower arch bars 8 mayconveniently be formed from angle members having the flanges 9 disposed at right angles to each other. Intermediate the points of connection of the end portions of'the bars 8 with the compression member 2 and the points of connection between the said bars 8 and the strut, one of the flanges 9 of each of the said bars 8 is warped or turned substantially on a helical curve so that the endportions 10 of each bar 8 lie in the plane of the upright flange 9 thereof.

Referring now to the form of strut memher 3 illustrated in the drawings, it'will be' observed that for convenience the top member 41, the columns 5 and the bottom memher 6 are all integrally connected preferably by casting the entire'strut member as a unit.

The bottom member 6 is conveniently ma de of greater width than the width of the column members 5, and is providedwith a pair of downwardly extending flanges 11. The

"latter are, for convenience, spaced inwardly from the outer. edges of the upper spring .plank seat 12 of the member 6, and if desired a plurality of strengthening ribs, such as 13, may be provided to connect the .said flanges to the outwardly extendingportions of the seat 12. .The end portions of the member 6 which also form the base of the respective columns 5, 5 are upwardly inclined as indicated at 111. The column memhere have been, for convenience, illustrated.

as formed .from'H shaped portions 15, the laterally extending flanges ,16 thereof being connectedat spaced points by webs 17. The

inner transversely extending web 16 of each column member is'preferabIy' thickened as I rality of openings 19through which the shown at 18 adjacent the 1 upper portion thereof, and may bejprovided with-a plus bolts 20, or other'equivalent fastening means which serveto connect the bolster guide plates 21, may extend.

In Figs. 11; and 12 i have illustrated a,

slight modification of this form of construction. In this form the column webs 16 are provided with countersunk'seats 22 each of which is adapted to receivethe ggii'de plate 21, the latter being furnishe with a countersunk seat 23 andsa plurality of open ings 24swhich, when the plates are in position, aline with openings 19 in the web 16 and in place of the bolts 20 T provide a U- shaped clip 25 the arms'of which extend through the openings '-24 and 19 and are adapted to be'bent as shown at 26 over the rounded projections 27 to maintain the guide plates in position; It will be understood of 'therethrough of course that this form of guide plate may be substituted for the form shown in Figs. 1, 2

and 3 of the drawings, if desired.

Adjacent the upper ends of each column 5 there is provided a frusto-conical seat 28,

clearly shown in Fig. 5. Each of these seats opens on the inner face of the column and each is adapted to receive one of the brake hanger brackets 29 which are also provided with frusto-con cal bearing portions which cooperate with the correspondingly formed wallsof the seats 28. The web 31,

which substantially closes the inner end of the recess 28, is preferably provided with a key hole slot 32 and each brake hanger bracket may be furnished with a pair of lugs'33 which, when the brackets are in position, engage the side edges of the slot 32 and hold the bracket from rotation in the seat 28.

nut 34, and if desired a washer 36 and a lock washer 37 may be interposed between the nut and the outer face of the web 31.

The brake hanger brackets are so formed as to have a tape'r'fit within the recess '28, andare preferably driven into these recesses. It will be noted, however, that in case the brake hanger bracket 29 should be broken in service it may be readily detached and a new l bracket substituted therefor without detriment to the truck side frame.

The upper member 1 of the strut is pref- ;erably designed so as to have a taper fit between the side flanges 38 ofthe top arch or compressionbar 2, this member being conveniently formed as a channel bar.

At the opposite ends of the compression bar 2 are provided journal box seats 39 each of which may be conveniently formed as a casting having abase member 40, up

that an opening 48 isprovided in the web of the compression member 2 adjacent the I ends-thereof, the purpose and object of the said openings being to permit the insertion the inner journal box bolt 47.

The lower portion of connect-ed to the strut member preferably 49 which are clearly shown in Fig. 4. The said tie members are convenientlyformed from a sheared bar 50, the bar being sheared and bent substantially in the form of an Each bracket ispreferably main- .tained in position by means of a bolt 35 and each journal box is means of the journal box tie members the other at their outer ends, and the jour nal box bolts 47 preferably extend-through alined openings which are provided-in both of the said bars. The inner ends of the said bars are connected to'the flanges lief-the strut 3" and the rivets .51 which serve to connect the same also form additio'nalfisecuring means for connecting the tension bars to the said strut. The transversely disposed flanges of both pair of. journal box tie plates are cut away as at 52 so as to permit the rivets 53 to be driven, the said rivets 53 passing through the portions 14 of the lower member 6 'of the strut and through the transversely disposed flanges 9 of the tension bars 8.

It will be noted that the tension bars 8 are riveted to the journal box seats andare also riveted to the compression bar 2, and that the latter rivets extend through the flanges 38 of the bar 2 and through the flanges 41 of the journal box seats .39, and that additional rivets are provided for connecting the compression bar 2'to the journal box seat. It will also be observed that the inters'ection'of the bars; 8 with the compression bar 2 is closely adjacent the vertical planes passed through the centerof the truck axle, and that while this inward spacing of the points of connection of thebars-8 and 2 from. the vertical planes passing through the car axles will produce a cantilever action in the jour--- nal boxseat members, the reaction point of the cantilever so formed, lies within the point ofunion of the compression and tension bars 2 and 8, respectivelyfand therefore this reaction Will be taken by bothjthe compression and tension bars.

It Will also be observed that by providing journal box tie members of the form shownf "arch meii ber, a .plurality of angle shaped and described herein, and by 'conneeti nlg' these tie members to the journal boxes in the manner shown, I greatly strengthen the side frame against lateral twisting, the

said journal box tie members acting as a.

truss to prevent this twisting movement.
